| Abstract | ||
| ٍTo investigate the impact of Enterococcus faecium as a probiotic in the performance of layer male chicks and some aspects of immunity, Newcastle disease antibodies and the blood picture, this bacteria was given in the feed of layer male chicks with a dose rate of 1.5 gkg of feed, each kg of feed contained (5×1011CFU) along the experiment which last 57 days. 150 male chicks were divided into five groups, the 1st group was given the probiotic in the feed, the 2nd group was given the probiotic and was exposed to bad ventilation and high temperature as a stress, the third group was given the probiotic and chlortetracycline in the feed, the fourth group was given the probiotic and then infected with E. coli on day 21 of the experiment, and the fifth group was given the feed only without the probiotic as a control group. Results showed that giving Enterococcus faecium in the feed had insignificant effect on Newcastle antibodies tested on day 37 of the experiment, and the effect was significant on day 57. Also, the differential count of the white blood cells was increased while the heterophilelymphocyte ratio was decreased in the groups which were given probiotic, compared with the control. | ||
